According to famed Harvard law professor Alan Dershowitz, President Donald Trump was within his authority to tell FBI Director James Comey not to prosecute former national security adviser Michael Flynn. Dershowitz said on Saturday on the on "CNN Newsroom With Ana Cabrera" that there are two remedies for those who oppose Trump’s dismissal of Comey: either "amend the Constitution, [or] don't vote for him."

Dershowitz, who is an expert on the Constitution, said, "But don't try to expand the existing criminal law in violation of civil liberties to do what Stalin did, where [secret police chief Lavrentiy] Beria said, 'Show me the man, I'll give you the crime. That's not America."

He went on to say, "The problem with impeachment is exactly what Candidate Trump did during the campaign – and you can't impeach a president who ran and won based on all the things he's done, all the things he's now doing." Dershowitz said, "There's not that much new that would warrant either an impeachment, certainly not a criminal prosecution."
